Title: Web and method and apparatus for handling same
IPC: G01N27/82
Filed: 1974-05-02
Abstract: 1450667 Controlling web feed EASTMAN KODAK CO 2 May 1974 [4 May 1973 (2)] 19318/74 Heading B8R [Also in Division G3] Defective areas of a web, e.g. of photosensitive material are rendered identifiable by coating the back of the web with an array of spaced markings in magnetic ink and saturating the markings over the defective areas. A number of suitable webs are described (Figs. 1-4, not shown) and a further magnetic edge stripe (17) may contain information as to footage, inventory &c. The web 11, Fig. 5, is drawn from a roll 20 and the ink markings are applied by a print roll 24 from a transfer roll 27 running in a bath of ink 25. A polyethylene coating is then applied by a bath 35, and the magnetic markings are degaussed by erase magnets 37 before a photosensitive layer is applied by coating hopper 41. Defects in this layer are detected at a scanning station comprising a laser 49, oscillat. ing mirror 50, and transversely spaced photocells 51. A defect causes one or more of the cells 51 to generate a signal which is fed to a computer 52 and used to energize appropriate magnetic heads 54 to saturate the markings over the defective area. The web is then slit and re-reeled. Each reduced web 60, Fig. 6, is passed from a roll 59 to a take-up roll 64. Transversely spaced transducers 70 produce signals in response to any saturated markings, the signals passing via an amplifier 80 and voltage discriminator 87 to a pulse storage circuit 84. On the stored voltage reaching a preset amplitude as determined by a staircase generator 85, a circuit 86 feeds a pulse to control unit 83 to stop the web drive motor 65 and reverse the web, bringing the defective area adjacent knife 72 for its removal. The reversing distance is determined from the integral of the output of tachometer 81 after detection of the defect. Defects below a certain size together with transients, e.g. picked up by the transducers 70 are rejected since a preset number of pulses must be received by the generator 85 within a certain interval. Environmental noise is rejected by use of a second channel 90 the output of which is fed to the gate of an FET 101. Any signal picked up simultaneously by an antenna 99 and the transducers 70 is leaked to earth via the FET and a resistor 104 which determines the sensitivity of the circuit.

[Class 56.] Blowing.-A ring mould for a press-andblow machine is made in one piece and has on its inner surface a shallow groove which engages the neck of the parison and enables the mould to support it during the subsequent blowing operation. The ring mould 1 is supported by a nut 2 below a funnel 3 through which charges of glass enter the ring and an associated parison mould 7. A shallow groove 9 is formed on the inner surface of the ring 1, the depth and width of the groove being of the order of one per cent of the internal diameter of the ring. A. tubular ejector 4 slides through the ring, and a pressing plunger 5 slides within the ejector. In use, a charge of glass 6 is pressed to form a parison, and glass enters the groove 9 and forms a ridge by means of which the ring 1 is enabled to support the parison while it is being blown in the finishing mould. After the completed article has been detached, the glass remaining in the ring 1 is removed by moving the ejector 4 downwards. The ring may be slightly conical to facilitate the removal of the remaining glass. The Specification as open to inspection under Sect. 91 (3) (a) describes also a construction in which the hot glass is caused to adhere to the ring mould, the groove 9 being dispensed with. This subject-matter does not appear in the Specification as accepted.
